  If you want your code to be portable, don't use the return-from-main
method.  Any program that you might want to port should use exit(rc)
to return a non-zero exit code.  This is the only method that works
under all C compilers and since exit() is quite offen included in the
initial object-code module it's not likely to make your program much
larger...
